Product Details

Allura Red is a dark red, uniform, odorless powder. It is soluble in water, glycerin, and propylene glycol, slightly soluble in ethanol, but insoluble in oils and fats. When dissolved in water, it forms a slightly yellowish-red solution. It exhibits strong resistance to light and heat but has poor resistance to alkalis and redox reactions, similar to other diazo red pigments.

Allura Red shows good stability in aqueous solutions containing sulfur dioxide or hydrogen ions at pH levels of 3 or higher. It has strong color fastness, appearing red in neutral and acidic solutions and dark red in alkaline environments.
